Stroma is the ground matrix of:
Correct answer: D. Chloroplast
- A. Lysosomes
- B. Ribosomes
- C. Oxysomes
- D. Chloroplast
Explanation
The correct answer is chloroplast. The stroma is the ground matrix of a chloroplast, which is crucial for the photosynthesis process. It is the site for the Calvin cycle, where carbon fixation takes place. The other options are incorrect: Lysosomes are involved in waste processing, ribosomes are involved in protein synthesis, and 'oxysomes' is not a recognized term in cellular biology.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
